摘要:
琼东南盆地深水区松南低凸起中生界花岗岩潜山领域勘探获得重大突破,揭示该盆地深水区基岩潜山领域具有较大的勘探前景,裂缝是影响该领域潜山储层发育主控因素之一。利用成像测井、井壁取心和薄片分析等资料,对松南低凸起Y8区中生界花岗岩潜山天然裂缝发育特征及形成机理进行了分析,结果表明:该地区中生界花岗岩潜山储层发育构造裂缝、溶蚀裂缝和成岩缝等3种类型,以发育中—高角度构造缝为主,多为NNW—SSE走向,其中90%为未充填缝及有效缝,主要为3期发育,垂向上可根据裂缝参数分为风化裂缝带和内幕裂缝带。岩性、构造及溶蚀改造是控制该地区潜山裂缝发育的关键因素,花岗岩储层长石与石英含量超过80%,有利于裂缝发育; 印支期以来的多期构造运动有利于形成网状裂缝系统,大气淡水及深部热液溶蚀改造进一步增大了裂缝发育深度,进而改善了花岗岩储层物性,扩大了花岗岩储层规模,并提高了油气产能
Abstract:
Significant breakthroughs have been achieved in the exploration of Mesozoic granite buried hill in the Songnan low uplift of deep water area of Qiongdongnan basin, which reveals that the bedrock buried hill in the deep water area of the basin has a sound prospect for exploration. One of the main factors that affect the development of buried hill reservoirs in this area is fractures. Based on data of image logging, sidewall coring and thin section analysis, the development characteristics and formation mechanisms of natural fractures in Mesozoic granite buried hill of Y8 area in Songnan low uplift have been studied. The results show that fractures developed in Mesozoic granite buried hill reservoirs are mainly of three types: tectonic fractures, dissolution fractures and diagenetic fractures, dominated by medium-high angle tectonic fractures. These fractures are mostly of NNW—SSE strike, and 90% of them are unfilled and effective fractures that mainly developed in three stage. Vertically, these fractures can be divided into weathered fracture zone and inner fracture zone with the different fracture parameters. Lithology, structure and corrosion transformation are the key factors that control the development of buried hill fractures in this area. The high content of granite feldspar and quartz in the granite reservoir(exceeding 80%)is conducive to fracture development. Multi-phase tectonic movements since the Indosinian are conducive to the formation of networked fracture systems. Atmospheric freshwater and deep hydrothermal solution alteration further increase the depth of fracture development, resulted in the amelioration of physical properties of granite reservoirs, expansion of granite reservoirs, and the improvement of oil and gas production capacity
